- Really? You seem to know a lot more about the internals of Commodore Engineering

- take a look at the motherboard sometime. There, in the bottom right hand side,

- Hmm. Lets see. Nope, according to the AA specs (I have them here, written by the
- chip designers themselves), Alice can only address 2Mb of Chip RAM. But I bow to
